Cash compensation. The company will pay you an hourly rate of $15.00 per hour with a twelve-month guaranty, from your hire date, of $40,000, payable in accordance with the company's standard payroll schedule.

(This is what my job offer contract states and I'm a bit confused by it. Does this mean I will only get $15.00 per hour so $1200 per two weeks before taxes? What exactly does the guaranty, from your hire date, of $40,000, mean?
Will i get $40,000 for only the first year but after that only $15.00 per hour? If the guaranty is $40,000 why do they put $15.00 per hour? Any help is greatly appreciated.
